Republican lawmakers in North Carolina have passed new restrictions on the state's abortion clinics, CBN News reports. The bill also mandates that a doctor be physically present during abortions, including those induced by drugs. The law's passage comes as new polls show that most Americans favor restricting abortion at 20 weeks of pregnancy, rather than the 24-week mark established under current law. A new Washington Post/ABC News poll found that 56 percent support those limits. Another 10 percent of those surveyed would prefer to outlaw abortion in the United States altogether or limit it earlier than 20 weeks after fertilization. More than half -- 54 percent -- say they oppose state laws that make it more difficult for abortion clinics to operate compared to 45 percent who support such legislation. An NBC News/Wall Street Journal poll found similar results. Meanwhile, 55 percent of respondents say abortion should be illegal in all or most cases.
